Its representaUves occur as trees or shrubs in eastern North America, Central America, South America and Bqrope but are most abundant In Asia. The White Mulberry (Moms alba L.) a native of Asia, has been planted extensively In this State, and In some localities has escaped cultivation. FOEM—Usually attains a height of 36-50 ft. with a diameter of 12-18 inches but may reach a height of 70 ft. with a diameter of 8 feet. Largest in Ohio and Mississippi valleys. Trunk usually short, subdividing near the ground. Crown usually broad, round-topped, and dense. BAEK—Begins to roughen about third year by splitting longitudinally or diagonally. On older trunks rather thin, dark graylsh-brown, peels off in long narrow flakes which somewhat resemble the flakes of Catalpa bark. See Pig. 76.

A milky juice is excreted from twigs If they are cut or punctured. BUDS—Alternate; terminal bud absent; ovate, round In cross-section, sharp-pointed, about 2/6 of an inch long, sllghUy divergent and laterally Inclined, covered by 8-0 exposed bud-scales which are 2-ranked, greenish-brown to greenish-red with darked margin. Buds are located on twig enlargements. A bud is often found at end of twig; It is not a terminal bud but an axUlary one sometimes called a pseudo-terminal bud, which means false terminal bud.
